Bangladesh-Myanmar Maritime Boundaries: Conflict and Cooperation

The maritime boundary dispute between Bangladesh and Myanmar represents one of South Asia’s most complex territorial conflicts, centering on competing claims over the resource-rich waters of the Bay of Bengal. This decades-long disagreement has profound implications for both nations’ economic development, resource exploitation rights, and regional security posture. Despite the International Tribunal for the Law of the Sea (ITLOS) ruling in 2012 that partially resolved the dispute, underlying tensions persist alongside emerging challenges related to refugee crises and changing geopolitical dynamics.

Historical context of the Bangladesh-Myanmar maritime dispute 🔗

The maritime boundary disagreement between Bangladesh and Myanmar dates back to Bangladesh’s independence in 1971. Initially, the dispute centered on overlapping claims to territorial waters and continental shelf boundaries in the Bay of Bengal. The conflict intensified during the 1970s and 1980s as both nations recognized the significant hydrocarbon potential beneath these contested waters.

Several key historical milestones shaped this dispute:

• 1974 Agreement: An initial agreement between the two countries established a partial boundary but left significant areas unresolved.
• 2008 Naval Confrontation: Tensions escalated when both countries deployed naval vessels to disputed waters after Myanmar began exploration activities near contested areas.
• 2009 UNCLOS Submission: Bangladesh submitted its continental shelf claims to the UN Commission on the Limits of the Continental Shelf, asserting rights beyond 200 nautical miles.
• 2009-2012 ITLOS Proceedings: After bilateral negotiations failed, Bangladesh initiated proceedings at the International Tribunal for the Law of the Sea.

Legal frameworks and the 2012 ITLOS verdict 🔗

The 2012 ITLOS ruling marked a watershed moment in the dispute. The International Tribunal for the Law of the Sea delivered a verdict that offered partial satisfaction to both nations while establishing a definitive maritime boundary. Understanding this legal framework is crucial to comprehending the current status of relations.

Key elements of the ITLOS ruling 🔗

The tribunal’s decision incorporated several crucial elements that reshaped the maritime boundary between the two nations:

• Equidistance methodology: The tribunal rejected Myanmar’s strict equidistance approach, which would have disadvantaged Bangladesh due to its concave coastline.
• Angle-bisector method: Instead, ITLOS employed an angle-bisector method that provided Bangladesh with a more equitable share of maritime territory.
• Continental shelf rights: Bangladesh was granted rights to a continental shelf extending beyond 200 nautical miles, a significant victory for Dhaka.
• Gray area: The ruling created a “gray area” where Bangladesh has seabed rights but Myanmar maintains water column rights, introducing a novel approach to maritime boundary demarcation.

The verdict awarded Bangladesh approximately 111,000 square kilometers of maritime territory-roughly 80% of its claimed area. While the ruling was legally binding and has been officially accepted by both nations, implementation challenges and interpretive differences persist.

Economic and resource implications 🔗

The economic stakes underlying this dispute remain substantial, with the Bay of Bengal containing valuable resources that both developing nations desperately need to advance their economic prospects.

Hydrocarbon potential 🔗

The Bay of Bengal contains significant hydrocarbon reserves, with estimates suggesting potential deposits of 15-20 trillion cubic feet of natural gas and substantial oil reserves. For energy-hungry Bangladesh, which faces chronic power shortages, securing access to these resources represents a vital national interest.

Following the 2012 ruling, Bangladesh has divided its maritime territory into 26 blocks for exploration and production, with several international oil companies expressing interest. However, development has been slower than anticipated due to technological challenges, investment uncertainties, and fluctuating global energy markets.

Fishing rights and marine resources 🔗

Beyond hydrocarbons, the dispute encompasses valuable fishing grounds that support millions of livelihoods in both countries. The Bay of Bengal supports over 500 fish species and provides critical protein sources for local populations.

The resolution of maritime boundaries has helped reduce incidents of fishermen being arrested for inadvertently crossing territorial waters. However, challenges remain regarding sustainable management of shared fish stocks, illegal fishing, and environmental protection measures.

The Rohingya crisis and its impact on maritime relations 🔗

While the maritime boundary dispute predates the Rohingya refugee crisis, this humanitarian catastrophe has created new tensions that complicate bilateral relations and, by extension, maritime cooperation.

Since 2017, over 700,000 Rohingya Muslims have fled persecution in Myanmar’s Rakhine State, seeking refuge in Bangladesh. This massive influx has created immense pressure on Bangladesh’s resources and infrastructure, particularly in the Cox’s Bazar district adjacent to the maritime boundary.

Maritime security challenges 🔗

The refugee crisis has introduced new maritime security challenges, including:

• Human trafficking: Criminal networks exploit desperate refugees, attempting to transport them via dangerous sea routes to Southeast Asian countries.
• Increased naval patrols: Both countries have increased maritime security operations, raising the risk of unintended confrontations.
• St. Martin’s Island: This small Bangladeshi island near the maritime boundary has become increasingly militarized due to security concerns related to refugee movements.

The humanitarian crisis has complicated diplomatic relations, making cooperative management of shared maritime resources more challenging. Bangladesh has consistently called for Myanmar to create conditions conducive to Rohingya repatriation, while Myanmar has been reluctant to address the root causes of the exodus.

Cooperative mechanisms and future prospects 🔗

Despite persistent tensions, both countries have established some cooperative mechanisms to manage their maritime relationship. These initiatives offer potential pathways toward more constructive engagement.

Joint monitoring mechanisms 🔗

Following the ITLOS ruling, Bangladesh and Myanmar established joint monitoring committees to oversee implementation of the verdict. These technical bodies meet periodically to address boundary demarcation issues and prevent misunderstandings that could lead to confrontation.

Additionally, naval communication channels have been strengthened to reduce the risk of accidents or miscalculations in contested waters. These confidence-building measures represent modest but significant steps toward normalized maritime relations.

Regional frameworks for cooperation 🔗

Both nations participate in regional frameworks that provide platforms for maritime cooperation:

• BIMSTEC: The Bay of Bengal Initiative for Multi-Sectoral Technical and Economic Cooperation includes both countries and addresses shared maritime challenges.
• IORA: The Indian Ocean Rim Association provides another forum for dialogue on maritime issues.
• BCIM: The Bangladesh-China-India-Myanmar Economic Corridor initiative has potential implications for maritime cooperation, though progress has been limited.

These multilateral frameworks offer institutional mechanisms that can complement bilateral efforts and potentially reduce tensions over maritime issues.

Geopolitical dimensions of the dispute 🔗

The Bangladesh-Myanmar maritime boundary dispute unfolds within a broader geopolitical context that includes the interests and influence of regional powers, particularly China and India.

China’s influence and interests 🔗

China maintains close relations with Myanmar while also investing heavily in Bangladesh. Chinese interests in the dispute include:

• Belt and Road investments: China has developed port facilities in both countries, including the Kyaukpyu deep-sea port in Myanmar.
• Energy security: China has invested in offshore energy exploration in Myanmar’s waters and built oil and gas pipelines from Myanmar’s coast to Yunnan Province.
• Strategic access: The Bay of Bengal offers China potential access to the Indian Ocean, supporting its “string of pearls” strategy.

India’s strategic concerns 🔗

India views the Bay of Bengal as part of its natural sphere of influence and has concerns about China’s growing presence in the region. India’s interests include:

• Security concerns: India closely monitors Chinese activities in the Bay of Bengal, which it considers vital to its maritime security.
• Economic ties: India has strengthened economic and defense cooperation with Bangladesh, partly to counter Chinese influence.
• Regional leadership: India positions itself as a responsible regional power that can help mediate maritime disputes.

These geopolitical dynamics add another layer of complexity to the bilateral maritime relationship between Bangladesh and Myanmar.

Environmental and climate change considerations 🔗

Beyond political and economic factors, environmental considerations increasingly influence maritime relations between Bangladesh and Myanmar. The Bay of Bengal faces severe environmental challenges that transcend national boundaries.

Shared environmental vulnerabilities 🔗

Both countries face similar environmental threats in their maritime domains:

• Climate change impacts: Rising sea levels threaten coastal communities and could potentially alter maritime boundaries over time.
• Extreme weather events: Increasingly powerful cyclones affect both countries’ coastal areas, requiring coordinated disaster response.
• Marine pollution: Industrial runoff, plastic pollution, and oil spills damage the shared marine ecosystem.

These common challenges create opportunities for environmental cooperation that could build trust and facilitate broader maritime cooperation.

Potential for environmental cooperation 🔗

Environmental initiatives offer a promising avenue for confidence-building measures between the two countries. Potential areas for cooperation include:

• Joint marine scientific research: Collaborative studies of marine ecosystems could benefit both nations while building scientific ties.
• Disaster warning systems: Shared early warning systems for cyclones and tsunamis would protect coastal communities in both countries.
• Sustainable fisheries management: Coordinated approaches to fisheries management could prevent overfishing and protect livelihoods.

Conclusion: Balancing competition and cooperation 🔗

The Bangladesh-Myanmar maritime boundary dispute represents a complex interplay of legal, economic, political, and humanitarian factors. While the 2012 ITLOS verdict provided a legal framework for managing the dispute, full normalization of maritime relations remains elusive due to the Rohingya crisis and broader geopolitical tensions.

The future trajectory of this relationship will depend on how both countries balance competitive interests with opportunities for cooperation. Progress in addressing the Rohingya crisis, developing joint resource management mechanisms, and building environmental cooperation could create positive momentum toward more constructive maritime relations.

As the Bay of Bengal continues to grow in strategic and economic importance, the management of this maritime relationship will have significant implications not only for Bangladesh and Myanmar but for regional stability and prosperity in South Asia as a whole.

What do you think? How might addressing shared environmental challenges in the Bay of Bengal serve as a potential bridge between Bangladesh and Myanmar despite their ongoing political differences? Could maritime cooperation eventually contribute to resolving the broader humanitarian crisis affecting the region?
